This is not actually a problem with Opera, but rather a request for clarification on how the browser works. I work for Seesaw, answering emails to help solve customer problems. We've recently seen an uptick in tickets where PDFs show up blank when uploaded to a Seesaw post. To quickly explain that, Seesaw users can upload PDFs to a post. This converts the PDF into movable, resizable images across multiple pages. The issue being reported will make a 5 page PDF display as 5 seemingly blank pages on Seesaw; these blank images can still be moved and resized. It does not happen with all PDFs, so normally we would assume there is a corrupt asset in the PDF itself. However, customers have reported that when they tested other browsers, Opera is the only browser where uploading PDFs works properly. Our Research/Testing squad has done a lot of research as to why it might not be working in other browsers, but we are wondering why Opera works. We know that Opera has built-in compression technology. Could this be compressing/repackaging the PDFs, causing Opera users not to run into the same issue?
